I just picked up a MD3000 to add to my 2950.  I've put in the P5 SAS card, the 2950 sees it.  I've loaded up the MD3000 with drives and configured all the drives as a raid 5 with one spare.  I can get to the MD3000 via out of band connection, everything looks great, but the 2950 does not see the virtual drive on the MD3000.  I've tried to set up ISCSI but it does not see the MD3000.  I'm using Windows Server 2012.
